以三齿席夫碱配体H2L{1-苯基-3_{(2.羟基苯)亚胺}-1-丁酮)和单齿N一杂环[咪唑(Himdz),2-甲基咪唑(Mimdz)}与Ni(OAc)2·4H20进行配位反应,得到2个配合物[Ni(L)(Himdz)}(1),[Ni(L)(Mimdz)](2)。并用元素分析,FTIR和X-射线单晶衍射进行了表征。在固体状态,配合物1和2都属于单斜晶系,P21/c空间群,分子间通过C-H…Л相互作用形成二聚体,二聚体中的每个分子通过N-H…0氢键向空间扩展成一维锯齿链状结构。初步研究了配体和配合物的体外抑菌活性,结果表明,配合物1和2具有一定的抑菌活性。
The two nickel (//) complexes [Ni(L)(Himdz)](1).[Ni(L)(Mimdz)](2) were synthesized from the reaction of tridentate Schiff base (1-phenyl-3-[(2-hydroxyphenyl)imino]-l-butanone) (H2L) and monodentate N-heterocycles [imidazole (Himdz), 2-methylimidazole (Mimdz)] with Ni(OAc)2.4H20 and characterized by elemental analysis, IR, 1H NMR spectroscopy. An X-ray structure determination of the complexes has been completed. In the solid state, both [Ni(L)(Uimdz)] (1), [Ni(L)(Mimdz)] (2) crystallize in P2,/c space groups, and exist as dimers due to intermolecular C-H ...rr interactions. Each of the dimeric molecules forms a one-dimensional zigzag chain via intermolecular N-H ... O hydrogen bonds involving the heterocycle N-H group, respectively. The antibacterial activities of the ligand and complexes were tested against seven kinds of bacteria. The results show that the complexes 1 and 2 possess inhibiting effects. CCDC: 695200. 1:6959.01 2
